Video: Watch the laser light move

Please see a pulse of laser light moving, touch the mirror and bounce it in another direction, then watch the laser pulse move through the air, changing its properties when passing through a thin layer of material. All of these images were captured by a 100-billion-frame 1-second speed camera, called CUP - compressed ultra-fast photography , which could be translated as ultra-fast compression of images , enabling the camera to create images Better with less data.

Movement speed of light

In fact, this camera is not the fastest camera in the world yet, the fastest is the one that has a speed of 1 trillion frames / second built in 2011, but the 1 trillion frame camera can only capture established situations. repetitive (situations created in the laboratory) while this 100 billion frame machine can be used outside reality, enabling scientists to record natural images while it occurs, images This image can work faster than the speed of light and still be recorded, making scientific research very easy.

Super-fast machines currently follow the "Streak Camera" technology - (an ultra-fast device used to measure the wavelengths of light) at a rate of about 10 million fps due to obstacles to the speed barrier of storage devices. as well as the data transfer speed inside the device. The new technology includes a series of interlocking devices, including microscopes and telescopes paired with lenses for event recording. The 100 billion frame / second camera is still based on the "camera streak" technology but has been improved in many technical aspects.
